Brothers engaged in network projects understand that the proxy IP is like a delivery boy, slow delivery and always lost certainly can not be. Today, we will teach the guys a few earth methods, with their own tools can be measured which proxy IP is a pitiful goods.

Tips for measuring speed

First, save the list of IPs to be measured into a txt file, which is recommended.ipipgo online detection toolThe fact that you don't have to install software is really nice. Focus on three indicators:

Response time 20% -- directly pull black
Geographic location deviation -- don't believe what the advertisement says.

To cite a chestnut, the last time I measured an IP claimed to be in Shanghai, the results connected to the Yunnan server room, this kind of goods before it is too late to throw away.

Anonymity and other levels are ignored

Many agents will brag about high anonymity, we can only rely on our own verification. Use this command to check the request header:

curl -I --proxy http://IP:端口 http://checkip.ipipgo.com

Private Debugging Tips

Finally, I'll share a trick: usingMulti-node relay detection。比如先让美国节点请求日本服务器，再用日本节点回连国内，这种套娃测试能暴露出90%的问题IP。ipipgo的全球中继网络专门优化过这种场景，能压到300ms内。

Remember, a good proxy IP is like finding a date, it's useless to just look at the ads, you have to personally inspect the goods. If you're too lazy to use ipipgo, you can use it directly.Screened IP library, their home quality control report is more detailed than my baby's report card, with all indicators clearly labeled.
